Lesson 8.2 Ear Anatomy

Objective: Students will identify and labelthe parts of the ear.

The EarOuter Ear

The outer ear has 2 main parts: the external ear and the ear canal.

The external ear is the part of the ear thatwe can see on the outside of the head. Ithelps the sound to enter the ear.

The ear canal is a tube between the external ear and the eardrum. It guidesthe sound to the middle ear.

Middle Ear

The middle ear has 4 main parts: the eardrum,hammer, anvil, and stirrup.

The eardrum is a tight surface like the topof a drum. It jiggles or vibrates when thesound reaches it.

The hammer, anvil, and stirrup are thesmallest bones in the body and start tojiggle along with the eardrum when soundreaches them.

Inner Ear

The inner ear has many parts including thesemi-circular canals and the cochlea.

The semi-circular canals are curved tubes.

The cochlea is shaped like a snail shell.

The auditory nerve carries the sound messageto the brain. The brain understands themessage.

Lesson 8.3 Sound WavesObjective: Students will identify sound asenergy. They will identify pitch andexamine factors that determine high andlow pitch.

Sound Wave Demonstration

How does sound travel through air?

Vibrate

To move back and forth

Pitch

The highness or lowness of sound

Shorter object and faster vibration =

higher pitch

Longer object and slower vibration =

lower pitch

Lesson 8.4 HearingStudents will order the steps of hearingand identify the function of each partof the hearing process.

The outer ear is shaped like a funnel thatguides the sound wave into the ear.There is a reason why people whisper inyour ear (Matt.10:27). There is a reasonwhy we turn our ear in the direction ofsound when we want to hear something (Prov. 2:2).

Psalm 88:2 “May my prayer come before you;turn your ear to my cry.”

The shape of the ear did not happen byaccident. It is designed by a creative God.

Psalm 139:13 For you created my inmostbeing; you knit me together in my mother’swomb.

Lesson 8.6 Healthy Ears

Students will explore ways of keepingtheir ears healthy and preventing hearingloss.

Some simple things we can do to take care of our ears:

*Have ears and hearing checked regularly.*Never put anything into your ear canal! A Q-tip can be used to clean the external ear.*If you have ear pain or something inside your ear, let your parents know right away.*Don’t listen to very loud music.
